Struct uefi::proto::media::file::FileSystemVolumeLabel

#[repr(C)]
pub struct FileSystemVolumeLabel { /* private fields */ }

System volume label

May only be obtained on the root directory’s file handle.

Implementations

impl FileSystemVolumeLabel

pub fn new<'buf>(
    storage: &'buf mut [u8],
    volume_label: &CStr16
) -> Result<&'buf mut Self, FileInfoCreationError>

Create a FileSystemVolumeLabel structure

The structure will be created in-place within the provided storage buffer. The buffer must be large enough to hold the data structure, including a null-terminated UCS-2 name string.

The buffer must be correctly aligned. You can query the required alignment using the alignment() method of the Align trait that this struct implements.

pub fn volume_label(&self) -> &CStr16

Volume label

Trait Implementations

impl Align for FileSystemVolumeLabel

fn alignment() -> usize

Required memory alignment for this type

fn offset_up_to_alignment(val: usize) -> usize

Calculate the offset from val necessary to make it aligned, rounding up. For example, if val is 1 and the alignment is 8, this will return 7. Returns 0 if val == 0.

fn round_up_to_alignment(val: usize) -> usize

Round val up so that it is aligned.

fn align_buf(buf: &mut [u8]) -> Option<&mut [u8]>

Get a subslice of buf where the address of the first element is aligned. Returns None if no element of the buffer is aligned.

fn assert_aligned(storage: &mut [u8])

Assert that some storage is correctly aligned for this type

impl Debug for FileSystemVolumeLabel

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Identify for FileSystemVolumeLabel

const GUID: Guid

Unique protocol identifier.
